What are the four main functions of the placenta?

Functions of the placenta include gas exchange, metabolic transfer, hormone secretion, and fetal protection.

How does the placenta form quizlet?

The trophoblast becomes the placenta and chorion, while the embryoblast becomes the embryo, amnion and umbilical cord. The trophoblast cells begin to make hCG, a hormone that ensures that the endometrium will be receptive to the implanting embryo.

What is the role of the placental membrane quizlet?

To permit the exchange of oxygenated maternal blood with deoxygenated fetal blood.

Which is not a function of the placenta?

What are the abnormalities of placenta?

These placental disorders are called placenta previa, placenta accreta, placenta increta or placenta percreta.

What are the two functions of placenta?

The placenta is an organ that connects the developing fetus to the uterine wall to allow nutrient uptake, thermo-regulation, waste elimination, and gas exchange via the mother’s blood supply; to fight against internal infection; and to produce hormones which support pregnancy.

What are the five major functions of the placenta?

The placenta performs the following functions:

  • Nutrition: Food materials pass from the mother’s blood into the foetal blood through the placenta.
  • Digestion: The trophoblast ol the placenta digest protein before passing them into foetal blood.
  • Respiration: ADVERTISEMENTS:
  • Excretion:
  • Storage:
  • Barrier:
  • Endocrine function:

What three membranes make up the placenta?


  • The placenta is a fetal organ made up of its parenchyma, chorion, amnion, and umbilical cord.
  • After fertilization, the fertilized ovum evolves into a morula, which will develop into the embryo and fetal placenta.

What two parts make up the placenta?

The placenta is composed of both maternal tissue and tissue derived from the embryo. The chorion is the embryonic-derived portion of the placenta. It is composed of fetal blood vessels and trophoblasts which are organized into finger-like structures called chorionic villi.
